Abstract
This study evaluated the analgesia effect and the effect on adverse reaction of using dexmedetomidine (Dex) in post-cesarean section. Eighty women who had been performed caesarean delivery with combined spinal and epidural anesthesia were selected. The experimental group (group D) included 40 random patients and the control group (group C) included the other 40 women. Patients in group D were given ropivacaine hydrochloride and Dex while patients in group C were given ropivacaine hydrochloride and morphine. We assessed and recorded the patient status at 2, 6, 12, 24 and 48 h using Ramsay sedation scale and visual analogue scale (VAS) in resting state and coughing state and we also recorded their adverse reactions. Except for the first 2 h after surgery, group D gets a lower VAS score than group C all the time in either resting state or coughing state (p<0.05); at 12 h, group D had a lower Ramsay score than group C (p<0.05) and no significant difference during the rest of the time was found; group D had a significantly lower rate of nausea, emesis and pruritus than group C (p<0.05). In conclusion, the usage of Dex in analgesia for post-cesarean can increase the analgesia effect produced by local anesthetics, increase puerpera sedation scores and decrease adverse reactions.
